ENDOTHELIAL DYSFUNCTION

This study tests whether intermittent doses of fisetin, a compound found in fruits and vegetables, can improve blood vessel function and reduce stiffness in adults aged 65 and older. Researchers will measure changes in artery health and look at how fisetin affects aging cells and…

This study tests whether dulaglutide, a drug used in type 2 diabetes, can improve the function of small blood vessels in adults with type 1 diabetes. The goal is to see if it reduces oxidative stress and helps blood flow better in muscles. The trial was suspended and aimed to enr…

This study aimed to see if a simple blood test could find blockages in the tiny blood vessels of the heart in people who had a heart transplant. Researchers planned to take blood samples every three months for a year and check medical records for three years. However, the study w…

This study was planned to see if giving nitric oxide during heart surgery helps protect blood vessels in patients whose vessels were already not working well. It was an add-on to a larger trial, but was withdrawn before any patients were enrolled. The goal was to measure blood fl…

This study looks at 500 people who have chest pain but no major blockages in their heart arteries. Researchers use special tests during a heart catheterization to find out if the problem is tiny blood vessel disease, artery spasms, or other issues. The goal is to better understan…

This study was designed to see if giving nitric oxide gas during heart surgery changes levels of certain molecules linked to oxidative stress. It was an add-on to a larger trial and planned to include adults having elective heart surgery. However, the study was withdrawn before e…

This study looks at how the health of blood vessels and a person's genes might be linked to early signs of COPD and emphysema. Researchers followed over 4,300 adults from a larger heart study, measuring lung function and using CT scans to check for lung damage. The goal is to bet…
